Abstract

A method for identifying traffic information for at least one sub-link includes receiving traffic information including a sub-link identifier enabling a determination of whether the received traffic information includes sub-link information, traffic status information enabling a determination of traffic information for a sub-link, information identifying a link within which the sub-link is located, and sub-link location information enabling a determination of a portion of the link that corresponds to the sub-link. The method also includes determining, based on the sub-link identifier whether the received traffic information includes sub-link information and dependent on whether the sub-link identifier enables a determination that the received traffic information includes sub-link information.

Claims

1. A method for identifying traffic information for at least one sub-link, the method comprising:

receiving traffic information including a sub-link identifier enabling a determination of whether the received traffic information includes sub-link information, traffic status information enabling a determination of traffic information for a sub-link, information identifying a link within which the sub-link is located, and sub-link location information enabling a determination of a portion of the link that corresponds to the sub-link;

determining, based on the sub-link identifier whether the received traffic information includes sub-link information; and

dependent upon whether the sub-link identifier enables a determination that the received traffic information includes sub-link information;

associating the received traffic status information as sub-link traffic status information for the sub-link, and

enabling perception of an association between the sub-link and the link, and an association between the received traffic status information and the sub-link.

2. The method of claim 1, wherein receiving traffic information includes receiving a data length associated with the traffic information, a text name or description of the sub-link, and a start and end location of the sub-link.

3. The method of claim 1, wherein receiving sub-link location information includes receiving vertex, coordinate, or longitude and latitude information that corresponds to a location associated with the sub-link.

4. The method of claim 1, wherein receiving sub-link location information includes receiving vertex, coordinate, or longitude and latitude information that corresponds to the link.

5. The method of claim 1, wherein after the sub-link is determined to be within the link, receiving additional sub-link information to enable deletion of the sub-link.

6. The method of claim 5, wherein the sub-link is deleted only if the received additional sub-link information includes an identifier that enables a determination that the sub-link is to be deleted.

7. The method of claim 5, wherein the received additional sub-link information specifies the sub-link identifier and the identifier of the link.

8. The method of claim 1, further comprising receiving additional sub-link information after the sub-link is determined to be within the link, and using the received additional sub-link information to alter the position of the determined sub-link within the link.

9. The method of claim 8, wherein the received additional sub-link information includes at least one of a start location and an end location of the determined sub-link.

10. The method of claim 8, further comprising using the received additional sub-link information to extend or shorten a length of the sub-link.

11. The method of claim 1, further comprising receiving additional sub-link information after the sub-link is determined to be within the link, and using the received additional sub-link information to alter the position of the determined sub-link beyond location constraints associated with the link.

12. The method of claim 1, further comprising receiving information corresponding to a message management structure including information corresponding to a generation time of the information included in the message management structure.

13. The method of claim 12, wherein the generation time included within the received message management structure relates to the status information for the sub-link.

14. The method of claim 13, wherein the generation time included within the received message management structure relates to a plurality of message component structures that correspond to more than one of a predicted or current traffic tendency, a predicted or current amount of traffic, a predicted or current speed, and a predicted or current time to traverse a particular link.

15. The method of claim 12, wherein receiving information reflecting a message component structure includes receiving information associated with identification and configuration of the sub-link.

16. The method of claim 1, wherein receiving the traffic status information for the sub-link includes receiving information associated with at least one of a predicted or current travel speed on the sub-link, a predicted or current congestion level or amount on the sub-link, a predicted or current travel time to traverse the sub-link, or a predicted or current speed of travel on the sub-link.

17. The method of claim 16, wherein the traffic status information for the sub-link differs from traffic status information for the link.

18. The method of claim 17, wherein the traffic status information for the sub-link is received after receiving traffic status information that is configured to reveal status for the link, the sub-link status information being configured to enable updated status information for a portion of the link corresponding to the sub-link.

19. The method of claim 1, wherein receiving sub-link information includes receiving a text descriptor associated with the sub-link.

21. The device of claim 1, wherein the data receiving interface receives additional sub-link information after the sub-link is determined to be within the link, and the processing device is configured to use the received additional sub-link information to alter the position of the determined sub-link within the link.

22. The device of claim 21, wherein the received additional sub-link information includes at least one of a start location and an end location of the determined sub-link.

23. The device of claim 21, wherein the processing device is configured to use the received additional sub-link information to extend or shorten a length of the sub-link.

20. A traffic information communication device, comprising:

a data receiving interface configured to receive traffic information including;

a sub-link identifier enabling a determination of whether the received traffic information includes sub-link information,

traffic status information enabling a determination of traffic information for a sub-link,

information identifying a link within which the sub-link is located, and

sub-link location information enabling a determination of a portion of the link that corresponds to the sub-link;

a processing device configured to process the traffic information received from the data receiving interface and to determine sub-link status information based at least in part on the traffic information received.

24. The device of claim 20, wherein the data receiving interface receives additional sub-link information after the sub-link is determined to be within the link, and the processing device is configured to use the received additional sub-link information to alter the position of the determined sub-link beyond location constraints associated with the link.

25. An apparatus for identifying traffic information for at least one sub-link, the apparatus comprising:

means for receiving traffic information including a sub-link identifier enabling a determination of whether the received traffic information includes sub-link information, traffic status information enabling a determination of traffic information for a sub-link, information identifying a link within which the sub-link is located, and sub-link location information enabling a determination of a portion of the link that corresponds to the sub-link;

means for determining, based on the sub-link identifier whether the received traffic information includes sub-link information; and

means for, dependent upon whether the sub-link identifier enables a determination that the received traffic information includes sub-link information, performing the steps of;
